Abstract: TITLE OF THE INVENTION           Dielectric Composition for Forming Electric Current Regulating Junctions ABSTRACT OF THE DISCLOSURE A dielectric composition for forming electric current regulating junctions that are stable under high temperature conditions during electrical circuit manufacture and operation, which composition comprises a selected high glass transition temperature polymeric binder, for example, a polyimide, and a critical amount, by volume, of dispersed, insulatively coated metal particles, for example, aluminum particles.  The junc-tions are insulative when first formed, but when assembled in a circuit and treated with a high frequency, high voltage dis-charge of a Tesla coil, there is sufficient flow of electric current to make the circuit controllably active.  Thereafter, the electrically activated Junctions can be switched between low resistance and relatively high resistance values by supplying either an electric current or current pulse to effect transition to relatively high resistance or a high frequency, high voltage discharge to effect transition to low resistance.

Abstract: VACCINE FOR PROPHYLAXIS OF TRICHOPHYTOSIS IN HORSE            AND METHOD OF PREPARING SAME             Abstract The vaccine for prophylaxis of trichophotosis in horse is a suspension of microconidia of the immunogenic strain Trichophyton equinum in a physiological salt solution having the pH from 6.2 to 7.0, and the concentration of 30-45 million microconidia in 1 ml  of sterile saline solution.  The method for preparing the vaccine for prophylaxis of trichophytosis in horse consists in that the immunogenic culture Trichophytosis equinum is grown on a solid culture medium at a temperature of 26-28°C for 15-25 days until optimum amounts of micro-conida of said culture as accumulated, after which the bio-mass is separated, homogenized to prepare a suspension of separate microorganism cells, and the end product is finally isolated by lyophilic drying. The use of the vaccine, prepa-red by  the proposed method, rules out trichophytists morbidity among horses to abolish losses due to untimely sales of pedigree and sporting horses, and also prevents infection of man.  When tried on a mass scale, the vaccine proved highly efficaceous (95-98 per cent).
